Top panel: persistent emission pulse profile of the NICER data taken on 2020 April 28 (ObsID 3020560101), day 1 after the outburst onset (black dots and solid line). We exclude the first GTI during which the burst forest occurred. The rms pulsed fraction is 8% ± 2%. The light blue dots represent the peak times of the NICER bursts folded at the spin period of the source. We find no preference for burst peak arrival time with phase. The blue vertical dashed line is the phase of the FRB arrival time. Bottom panel: pulse profile of the persistent emission as observed during days 21–39 postoutburst (ObsIDs 3020560105–3020560119). The dotted lines are the phases of the two radio bursts observed by Kirsten et al. (2020). The rms pulsed fraction is 6.7% ± 0.8%. The two profiles, shown in the energy range 1.5–5 keV, are not phase-connected; their respective minima are shifted to phase zero. See text for more details.
